Two part paper on convective bursts in hurricanes published in Monthly Weather Review

These two papers analyze extreme upward air currents, called “convective bursts,” in hurricanes that have been believed to be important for hurricane intensification. We use the Weather Research and Forecasting (WRF) model to look at convective bursts in two hurricanes: Hurricane Dean from 2007 and Hurricane Bill from 2009. 125 more words

Paper on accounting for the location of dropwindsondes during measurements released online in the Journal of Atmospheric and Oceanic Technology

Summary: Hurricane Hunter aircraft have been releasing instruments called dropwindsondes to measure pressure, temperature, moisture, and wind speed and direction in hurricanes for two decades. Data from dropwindsondes released near the storms have led to better forecasts of where they will go, but improvements to forecasts of how strong they will get have lagged. 271 more words
